Exhaust Noise Testing
Many statutory bodies around the world currently mandate that vehicles comply with stationary exhaust noise tests specifications - Generally based upon the "SAE J1169 Measurement of Light Vehicle Exhaust Sound Level under Stationary Conditions"
In Australia the test requirements are ADR 28/01 stationary noise test and based upon SAE J1169. In fact, the above tests have identical test procedures and only the required limit varies:
SAE J1169 USA 95 dB
ADR 28/01 Australia 90 dB
The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983 noise level meter, specifically as illustrated in the diagram below. No other positioning is relevant! Noise tests are extremely specific in their scope and must be conducted very carefully!
Diagram from SAEJ1169 Testing Procedures
Engine RPM must be held steady at 75% of rated peak horsepower RPM.
Given the latter figure is 5,200 RPM for the XR6T, the test engine speed is 3,900 RPM for these vehicles.
Again, it must be emphasised, all facets of a noise test must be specifically followed for the test to have any meaning.
